Data Fields on the Map
The “Data Fields On?” option provides a map 
display (shown at right) with five user-selectable data 
fields along the right-hand side of the screen. Select 
this option when you wish to display additional on-
screen data — such as destination waypoint name 
(WPT), desired track (DTK), ground track (TRK), 
distance to destination (DIS) and ground speed (GS). 
If this option has been selected and the data fields 
are being displayed, “Data Fields Off?” appears as an 
option...

 NOTE: The on-screen traffic information (TRFC) oc-
cupies two data fields, leaving room to display only three additional data types. Traffic information is only available when the 500W-series unit installation includes connection to traffic information sources. See the 400W/500W Series Display Interfaces Pilot's Guide Addendum. 
Restoring Factory Settings
“Restore Defaults?” resets all five user-selectable 
data fields to their original factory default settings.

Terrain Operation
During power-up of the 500W Series unit, the 
terrain/obstacle database versions are displayed along 
with a disclaimer. At the same time, the Terrain system 
self-test begins. A failure message is issued if the test fails.  Garmin TERRAIN is a non-TSO-C151b-certified 
terrain awareness system provided as a standard feature 
of 500W-Series units to increase situational awareness 
and help reduce controlled flight into terrain (CFIT). 
TAWS is an optional feature on 500W-Series units....

44
Baro-Corrected Altitude
Baro-corrected altitude (or indicated altitude) is derived 
by adjusting the altimeter setting for local atmospheric 
conditions. The most accurate baro-corrected altitude 
can be achieved by frequently updating the altimeter 
setting to the nearest reporting station along the flight 
path. However, because actual atmosphere conditions 
seldom match the standard conditions defined by the 
International Standard Atmosphere (ISA) model (where 
pressure, temperature, and lapse...

To show or hide aviation data:
1.  Select the Terrain Page and press MENU. 
2.   Select “Show (or Hide) Aviation Data” and 
press  ENT. Pressing the  CLR key when the 
TERRAIN Page is displayed will also toggle 
aviation information on or off. 
Inhibit Mode
The Garmin Terrain system provides an “inhibit 
mode”. This mode is designed to deactivate Premature 
Descent Alert/Forward Looking Terrain Avoidance 
(PDA/FLTA) visual alerts when they are deemed 
unnecessary by the pilot. Flying VFR into an area...

46
Terrain Symbols
The following symbols are used to represent 
obstacles and potential impact points on the Terrain 
Page. Note that obstacle symbols are shown on display 
zoom ranges up to 10 
NM: 
The Garmin TERRAIN system uses yellow (cau
-
tion) and red (warning) to depict terrain information 
relative to aircraft altitude. Each color is associated 
with an alert severity level. Terrain graphics and visual 
annunciations also use these color assignments. 
 NOTE:  If an obstacle and the projected...

47
Database Versions
The version and area of coverage of each ter-
rain/obstacle database is shown on the Terrain Data-
base Versions Page, located in the AUX Page Group. 
Databases are checked for integrity at power-up. If a 
database is found to be missing and/or deficient, the 
Terrain system fails the self-test and issues a failure 
message. 
Terrain Database Information
Database Updates
Terrain/Obstacle databases are updated periodi-
cally with the latest terrain and obstacle data. Visit the

Forward  Looking Terrain Avoidance
The unit will issue terrain alerts not only when the 
aircraft altitude is below the terrain elevation but also 
when the aircraft is projected to come within minimum 
clearance values of the terrain. This alerting, called 
Forward Looking Terrain Avoidance (FLTA), is also pro
-
vided for obstacles. Any potential impact points will be 
depicted on the display. 
FLTA Severity Levels

TERRAIN  Failure Alert
The TERRAIN system continually monitors 
several system-critical items, such as database validity, 
hardware status, and GPS status. Should the system 
detect a failure, a message is annunciated “TERRAIN 
has failed”. 
“TERRAIN has failed” message
“TERRAIN  Not Available” Alert
The TERRAIN system requires a 3D GPS 
navigation solution along with specific vertical 
accuracy minimums. Should the navigation solution 
become degraded, or if the aircraft is out of the 
database...
